2-wire - ¼ NPT female

The WIKA TR34 miniature resistance thermometer is used as universal thermometers for the measurement of liquid and gaseous media in the range -50 … +250 °C (-58 … +482 °F). The instruments are intrinsically safe and suitable for use in hazardous areas. The WIKA TR34 can be used for pressures up to 140 bar with 3 mm sensor diameters and up to 270 bar with 6 mm sensor diameters, depending on the instrument version. All electrical components are protected against humidity (IP67 or IP69K) and designed to withstand vibration (20 g, depending on instrument version). The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the PC configuration software WIKAsoft-TT. Measuring range, damping, fault signal per NAMUR NE43 and TAG no. can be adjusted. Insertion length, process connection, sensor and connection method can each be selected for the respective application within the order information. The WIKA TR34 resistance thermometer consists of a thermowell with a fixed process connection and is screwed directly into the process. The electrical connection is made via an M12 x 1 circular connector. An adapter for electrical connection with angular connector per DIN EN 175301-803 is optionally available (industrial property rights registered under No. 001370985).

The high-quality WIKA PCS mechanical pressure switches have been developed especially for safety-critical applications with limited space. The high quality of the products and manufacturing following ISO 9001 ensure reliable monitoring of your plant. All wetted parts are from stainless steel as a standard. The switch enclosure is available in aluminium alloy or stainless steel. To adjust the setpoint, simply open the access cover plate. This access can be sealed as an option. The access to the terminal block for the electrical connection is protected by a screw-on lid, which is secured with a screw-type lock against unauthorised intervention. The pressure switches are fitted with one micro switch, which enables the switching of an electrical load of up to AC 250 V, 15 A directly. For lower switching power ratings, such as for PLS applications, argon gas-filled micro switches with gold-plated contacts can be selected as an option. For two separate circuits, the switches are also available in the version DPDT (double pole double throw). By using a diaphragm with antagonist spring as a sensor element, the model PCS pressure switch is extremely robust and guarantees optimal operating characteristics. For high setting ranges, a piston replaces or completes the diaphragm as a measuring element. The piston sensor element is designed for the specific requirements of liquid media.
